Taxonomic notes
Synonyms: Agave virginica Linnaeus; Manfreda tigrina (Engelmann) Small; Polianthes virginica (Linnaeus) Shinners.[1]
Varieties: none.[1]
Description
A description of Manfreda virginica is provided in The Flora of North America.
Distribution
M. virginica ranges from eastern South Carolina, central North Carolina, southwest Virginia, western West Virginia, southern Ohio, southern Indiana, southern Illinois, and Missouri, south to central peninsular Florida and Texas.[1]
Ecology
Habitat
This species grows in well-drained or poorly-drained slopes of longleaf pine forests, savannas, mesic pine-hardwood forest remnants, granite flatrocks, diabase glades, limestone and dolomite barrens and glades, xeric woodlands over mafic or calcareous rocks, sandhill woodlands, and dry roadbanks.[2][1] It prefers sandy loam habitats and upland Coastal Plain soils that have little slope and low fertility. [3] Additionally, it thrives in semi-shaded areas to open areas. Associated species include longleaf pine, wiregrass, and hardwoods.[2]
Phenology
M. virginica flowers from late May through August and fruits from August through October.[1]
Fire ecology
This species is found in annually burned areas[2] as shown by populations of Manfreda virginica known to persist through repeated annual burns.[4][5]
Pollination
M. virginica is pollinated both diurnally and nocturnally, with observations suggesting that bumblebees are the predominant floral visitors.[6] Bombus pennsylvanicus and Hemaris diffinis are critical diurnal pollinators; however, diurnally pollinated plants were observed to produce significantly lower seed set than nocturnally and open-pollinated plants.[6] Hence nocturnal visitors contribute more to M. virginica reproduction despite frequent diurnal visits.[6]
